At first I read OP's post between the lines then recognised familiar word "Rochelle Salt" and then quicly went to typing. 😀
Now I realised that the topic was mostly about the so called "Ground Box" and much less about AC passive filtering.
Grounding Boxes is new to me and I bet for many here too. I saw it before but was never interested. Will start to reasearch about the subject next week.
The goal is to self learn, separate marketing from what is known and shape the data of the design to common sense and logic.
It seems there is a few commercial ground boxes on the markets with different approaches.
And surprise surprise (for me) Shunyata too made their own. In fact two different boxes. One for chassis ground and another for signal ground.
I found one interesting video on youtube. Saw it at work with 20+ pauses because it was a bussy day. )
Here it is.
Firstly you must be aware that this is an interview of Caelin Gabriel (Shunyata Research CEO, founder and designer) where he promote and talk about Shunyata new at the time of interview products (grounding boxes) and interviewers are his dealers.
So just turn your internal sanity filter and recycle incoming info.
But interview and ground topic was interesting and I can't help but like the guy. Ha ha ha. )
I have a few quick speculations about how it works but really not enough data.

Lacking independent verification of the claims being made it's hard to put much credence into any of this. Or to know whether it is even relevant to your particular needs.
The title of this thread is "How to improve your AC power". That assumes to begin with that you have a problem. But you might not and could end up just wasting time and money chasing a non-problem.
A much better thread topic would be "How to measure your system for noise to see if it needs any improvement."

Reading this forum there are guliable people born every day and audio experts and manufacturers expliot these people with there guru hyperbole. The obsessive neurotic types get hooked in every time.this thread is a missmash of opions,no facts whatso over.oh did anybody mention the noise generated by so called linear power supplies used in most audio amplication.thats a fact .
I'm surprised motor / generator sets arent more popular if AC line noise was such a problem. Anywhere there's a buck to be made, someone would have removed the gas motor and installed an couple-few HP electric turning 3600 RPM or whatever. To be really sure, you could arrange it to be belt driven - no way any HF line interference is going to make it through the rubber belt.
Why, you could even make it variable speed like an old snowmobile transmission - then people could make claims like it sounds better at 67.2 Hz, or 53.5.
Or if the belts are too much and - anyone - is good with a conducting steel connecting shaft; get one of those variable frequency drives for the motor part. Variable output frequency - MMmmm!
Saw a little two-stroke one last week at a yard sale; pretty sure Harbor Freight origin, probably could have got it for next to nothin' - but alas, didnt realize the potential for DIY fully isolated AC. Instead, I thought "I'm not burning a mix, continuously in a fixed location - smoke up the whole neighborhood and I've got a 4 stroke one already".
You'd have to be careful with those; these days some of them have electronic inverters to make the AC part, I guess so they dont have tp regulate the speed, or for some other reason I dont quite understand. My old one makes power as long as it's spinning; 3600 RPM gives 60 Hz.

There are people so obsessed with trying to squeeze one more ounce of sound quality out of their system that they will fall for just about any of the snake oil salesmen who prey on them. And then they post stories here so that others like them can join in the charade.
I am interested in taking a break from the reported posts, so we are giving this one a break for the time being.
